Arnol Meeting House (1950)
I think this was the place where they had the meetings. The revival began slowly, but after the prayer meeting at 10a (see this website), the revival took off.
For more information see, ‘Sounds from Heaven, by Colin and Mary Peckham (for details of the 1949-52 revival), both published by Christian Focus Publications, p51, 213-8, 233-7.
